A3-package
(Package: A3) :
A3 Error Metrics for Predictive Models
A package for the generation of accurate, accessible, and adaptable error metrics for developing high quality predictions and inferences. The name A3 (pronounced "A-Cubed") comes from the combination of the first letters of these three primary adjectives.

a3
(Package: A3) :
A3 Results for Arbitrary Model
This function calculates the A3 results for an arbitrary model construction algorithm (e.g. Linear Regressions, Support Vector Machines or Random Forests). For linear regression models, you may use the a3.lm convenience function.
● Data Source:
CranContrib
● Keywords:
● Alias: a3

plot.A3
(Package: A3) :
Plot A3 Results
Plots an 'A3' object results. Displays predicted versus observed values for each observation along with the distribution of slopes measured for each feature.

a3.gen.default
(Package: A3) :
Stochastic Data Generators
The stochastic data generators generate stochastic noise with (if specified correctly) the same properties as the observed data. By replicating the stochastic properties of the original data, we are able to obtain the exact calculation of p values.
● Data Source:
CranContrib
● Keywords:
● Alias: a3.gen.autocor, a3.gen.bootstrap, a3.gen.default, a3.gen.normal, a3.gen.resample

plotPredictions
(Package: A3) :
Plot Predicted versus Observed
Plots an 'A3' object's values showing the predicted versus observed values for each observation.
● Data Source:
CranContrib
● Keywords:
● Alias: plotPredictions

a3.base
(Package: A3) :
Base A3 Results Calculation
This function calculates the A3 results. Generally this function is not called directly. It is simpler to use a3 (for arbitrary models) or a3.lm (specifically for linear regressions).
● Data Source:
CranContrib
● Keywords:
● Alias: a3.base

a3.lm
(Package: A3) :
A3 for Linear Regressions
This convenience function calculates the A3 results specifically for linear regressions. It uses R's glm function and so supports logistic regressions and other link functions using the family argument. For other forms of models you may use the more general a3 function.
● Data Source:
CranContrib
● Keywords:
● Alias: a3.lm
